I've read a lot of the report and two things are clear: That Sadaam was a real threat and that he respected only the use of overwhelming force. He considered all diplomatic and even military maneuvering short of all-out war, to be a sign of weakness. So much for the idea of using diplomacy and sanctions on these types.
And some of these weapons sites are thousands of acres in size.
How long do you think it will take to completely inventory them, especially in light of the fact that fighting is still going on?
I say our knowledge is incomplete, and will remain so for at least another decade.
